3 Claims.

This invention relates to a new and useful improvement in paper bottles. and containers, and, in particular, to a bottlemade from heavy paper or light board stock having a body, which is square or rectangular in cross-section, a bottom integral therewith, and inset somewhat above the bottom edge, a neck projecting from the upper edge of the body, which gradually tapers and approaches a round cross-secion which it acquires at its upper end, and which may be enveloped by an annular lip of a size adapted to receive any standard cap or closure such as that used for closure such as that used for closing glass milk bottles, for example.

Important features embodied in this invention are the strength and rigidity of the bottom, the stifiness of the neck and also the smoothness of.

its interior, which, although formed by pleating, presents a surface which is substantially as smooth and unbroken as that of a glass bottle, and the reinforcement of the vertical edges of the body by internal outstanding ribs, which cooperate with the bottom and the neck reinforcement to give the bottle extraordinary resistance to distortion or crushing, although it may be made from relatively light stock which ordinarily would respond without light pressure.

Since one of the important uses of this bottle is illustration in the drawings hereof and description herein is designed particularly for that service, so that standard filling and capping equipment, for which most dairies are now equipped, can be used without alteration. However, it will be understood to a bottle for this purpose or to the actual or relative dimensions shown.

Figures 14 and 15 illustrate schematically a method by which the bottom when otherwise completed can be inset sufliciently above the bottom edge of the bottle to insure that the bottle will sit on its bottom edge rather than on the bottom proper.

' and 5, by vertical scores 6 impressed from the inside or'back of the blank so that they form outwardly-projecting ribs at the vertical outer corners of the bottle.

Beginning at the point 1, which is the junction between the body and th neck of the bottle,

panels, 2, 3, 6 and 5 taper symmetrically to the top of the blank, the taper being such that when the bottle is f0rmed,3the edges 8 and Q of adjacent panels will meet throughout their length. Beyond the outer edge of one of the outer panels (5, for example) is a flap I0 which; when the bottle is formed, overlaps the outer edge of the opposite panel 2,-and is tightly secured thereto 7 i by a suitable,adhesive.

that the invention is not limited The tapering neck parts of panels 2, 3, d and 5 and the corresponding neck part of flap Ill are formed by score lines 12 and I3 forming integral I V-shaped pleatingsections II through the cen-, ter of which scorings 6 are extended to the top edge of the blank. Scorings l2 and I3 are irnpressed from the face or outside surface of blank beginning at the points i which are in transverse alignment at the point where the bottle body shoulder is formed and from which the bottle neck formed by the tapering panel sections taper upward to the bottle mouth. Sections above the upper edges of the neck panels with the apex of each angle at a score line 6 'so that when the bottle is formed, the upper edge of each pleat section II will be in alignment with the edges of the panels forming the bottle mouth and thereby form a level seat for the mouth lip or ring which is applied to firmly hold the pleats and to provide a seat for, the bottle closure.

The base of the bottle will be at the line 14, Figure 6A, at which point the blank has a transverse scoring' l5 impressed from the back or inside of 'the blank extending across the entire width of the panels 2-.5 including flap l0. Bei low this line are formed jive integral bottom cent the body panel by the longitudinal scorings 6. Panel 6 adja- 2 is a square section adapted to extend over the entire bottom area, and panels l1, l8 and I9 are rectangular sections half the width of the bottom area, and panel 20 is the width of flap l and its length is equal to the width of sections l1- -l9. I1 and I9 are provided with diagonal scorings 2l-22 and 23-44, respectively, impressed from the back or inside of the blank and extend from a mid-point on the edges of sections l1 and I9 to the corners at the junction of scorings 6 and l forming each of these sections into three triangular sections, indicated by reference numbers ll; 25 and 21 adjacent panel 3, and referenc numbers I9, 26 and 28 adjacent panel 5.

The various surfaces of the'bottom sections Bottom sections sections or panels l6, l1, l8, Hand defined adjacent the bottom by approximately twice the thickness of the stock from which the bottle is made. By causing die 3| to approach the bottom of the bottle and causing mandrel 30 to recede a little, the reduced end 32 wil1 force the bottom inwardly slightly, as shown in Figure 15, so that all layers of the bottom will lie above the bottom edge or chimb of the bottle. Since thi causes the edges of the bottom sections adjacent transverse scoring IE to fold upwardly, as shown in Figure 15, the extreme bottom edge of the bottle is provided with a reinforcement integral with the bottle body and bottom and when this reinforcement is firmly secured to the bottom edge of the bottle by adhesive, an extremely strong and rigid structure results: To this end it is desirable that adhesivebe applied to a narrow strip both above and below the transverse just described which form the bottom of the bottie, with the exception of those which constitute the inside and outside surfaces, should be coated with adhesive to stick them together so tightly as to make the bottom proof against leakage and also to give it the greatest possible strength and rigidity. A preferred distribution of adhesive on the inside and outside surfaces of the bottom sections, is indicated by the stippling in Figures 6A, 10, 11 and 12.

As shown in Figure 6A, bottom sections 18 and 20 have the adhesive on the under or outside, and section l6 has the adhesive partly covering the upper or inside. The clear surfaces of these sections when folded in become the upper layer or inner side of the bottom as seen in Figure 'l, the rectangular section l8 becoming one-half of the inner bottom surface and the blank part of section [6 and section 20 becoming the other half of the inner bottom surface.

From this blank the bottle may be made as follows: The blank is first folded upon scorings .6, around a mandrel corresponding in size and shape to the inside of the Bottle and flaps l0 and 20 are folded either inside or outside of the-outer edge of panel 2 and securely attached thereto by adhesion. Preferably fiaps l0 and 20 are secured to the inside of panel 2 since this produce the neatest appearance in the finished bottle and this method has been followed in the bottle shown in the drawings. The blank has now'assumed the shape of an open-ended tube of square crosssection as shown in Figure 10.

The next step is preferably to form the bottom. This is done by folding section I8 inwardly on scoring l5,'and the folding of, section [8 inward draws triangular sections and 26 of bottom sections l1 and I9, respectively, inward on scorscoring l5 all the way across the inside surface of the blank, as shown in Figure 6A.

The next step is to form the neck. This is done by bending the four tapering sections of panels 2-5 inwardly until the edges 8 and 9 of the adjacent tapering sections meet, as shown in Figure 8. This can be done by pleating section ll outwardly along scoring 6, l2 and I3, which is also shown in Figure 8. In this way a bottle neck having the shape and dimensions of the body shoulder is formed, but which gradually approaches a circular shape which it acquires at its upper end to form the bottle mouth. The interior surface of th neck is composed entirely of the tapering parts of the blank panels 2-5, the edges of which lie close together on the score lines l2l3 throughout their length so that the interior of the bottle issubstantialiy smooth and unbroken and very similar to that of an ordinary glass bottle.

The next step is to foldthe projecting pleats I I shown in Figure 8 upon the neck panels, preferably towards each other, as shown in Figure 9, so that they lie flat in opposite pairs against the outside of the neck panels. are integral with the neck panels there is no possibility of leakage in this portion of the bottle. They also form extremely efficient reinforcing and stiffening ribs for the neck, and since they .overlie the junction between adjacent edges of the neck panels and lie snugly against them, there are no recesses of any consequence into which liquid can pass. /As a matter-of-fact, when the bottle is coated with paraffin or other coating material, the minute space between the edges of adjacent panels will be filled so that the interior of the bottle is substantially smooth and unbroken as heretofore mentioned.

ings 22 and 23 as seen in Figure 11. Then sec-- tion I6 is folded inward on scoring l5, drawing triangular. sections 21 and 28 of bottom sections l1 and I9 inward on scorings 2| and 24 forming the two double-ply large triangular sections I'l and I9 as seen in'Figure 12. These triangular sections l1 and I9 are then folded inward to form the outer layer of the multiply bottom as seen in Figure 13.

The final step recess it slightly so that with respect to the bottom is to the bottle will stand upon its lower edge or chimb and not on the The upper end of the neck may be finished off in any suitable way as by a ring 33, which is usually channel-shape, so that it can be slipped down over both the inside and outside of the upper edge of the neck and secured thereto by contracting the ring from one or both sides in a manner which will insure that there will be no leakage as shown, for example, in Figures 5 and 6. Sincetliis ring is usually applied before the bottle is coated any minute spaces which may remain as theresult of the varying thickness of the neck will be filled.

duce Outstanding stiffening beads along the ver- Since these pleats body panels 2-5 are asansu tlcal corners of the body of the bottle. as best indicated in Figures 3, 7 and 9, at la.

Thus the bottle has a heavy rigid'recessed multiply bottom witha two-ply chimb, a body portion withstiflened corners and a neck portion also provided with stiffening folds, the effect of all of which, particularly when the ring 33 is added, is to produce a bottle made-from relatively light stock which is very resistant to crushing or'distortion from ,either the outside or the inside. It is obvious that the manufacture of the bottle requires relatively few and simple operations so that it possesses the additional extremely important characteristics of cheapness which not infreqeuntly are adequate so that no other adhesive need be used,
